Obtaining articles wihout journal subscriptions

We know it's frustrating that many articles we cite here are not free to read. One-off paid access fees are generally astronomically priced, suitable for such as "On a Heuristic Point of View Concerning the Production and Transformation of Light but not as a gamble on unknowns. With a median world income of US$ 9,373, for most of us US$ 42 is significant money to wager on an article's relevance and importance. 

  • Unpaywall offers a browser extension for Chrome and Firefox that automatically indicates when an article is freely accessible and provides immediate access without further trouble. Unpaywall is also unscammy, works well, is itself offered free to use. The organizers (a legitimate nonprofit) report about a 50% success rate
  • The weekly New Research catch is checked against the Unpaywall database with accessible items being flagged. Especially for just-published articles this mechansim may fail. If you're interested in an article title and it is not listed here as "open access," be sure to check the link anyway. 

How is New Research assembled?

Most articles appearing here are found via  RSS feeds from journal publishers, filtered by search terms to produce raw output for assessment of relevance. 

Relevant articles are then queried against the Unpaywall database, to identify open access articles and expose useful metadata for articles appearing in the database. 

The objective of New Research isn't to cast a tinge on scientific results, to color readers' impressions. Hence candidate articles are assessed via two metrics only:

  • Was an article deemed of sufficient merit by a team of journal editors and peer reviewers? The fact of journal RSS output assigns a "yes" to this automatically. 
  • Is an article relevant to the topic of anthropogenic climate change? Due to filter overlap with other publication topics of inquiry, of a typical week's 550 or so input articles about 1/4 of RSS output makes the cut.

A few journals offer public access to "preprint" versions of articles for which the review process is not yet complete. As it is the journal's decision to do so, we respect that and include such items in New Research. These are flagged as "preprint."

The section "Informed opinion, nudges & major initiatives" includes some items that are not scientific research per se but fall instead into the category of "perspectives," observations of implications of research findings, areas needing attention, etc.

What does "(provisional link)" mean?

When the input list for New Research is processed, some articles do not produce a result from the journal databases we employ. Usually this is because the publisher has not yet supplied information to for the given article. In these cases and in order to still include timely listing of articles, we employ an alternate search tactic. While this method is usually correct, sometimes the link shown will lead to an incorrect destination (available time does not always permit manual checking of these). We invite readers to submit corrections in comments below.

Each edition of New Research is reprocessed some two weeks after intitial publication to catch stragglers into the DOI ecosystem. Many "provisional links" will end up being corrected as part of this process. 


Please let us know if you're aware of an article you think may be of interest for Skeptical Science research news, or if we've missed something that may be important. Send your input to Skeptical Science via our contact form.

  1. I don't suppose anyone has seen or commented on Dan Pangburn 2021? —  


    'During the time period when water vapor (WV) and carbon dioxide (CO2) have been accurately measured worldwide, 1988-now, WV increase has been responsible for the human contribution to Global Warming/Climate Change with no significant net contribution from CO2."


    If so, a link would be much appreciated.

    [RH] Embedded link.

  2. Citizenschallenge @1 :  Dan Pangburn was a frequent commenter in the earlier years of SkS.  His track record for valid science is distinctly poor.

    I would be grateful to learn from you if Pangburn has come up with anything useful.   The importance of water vapor as a strong positive feedback on CO2's greenhouse effect is something well known to climate scientists for about a century.   So I would be interested to hear if Pangburn is making a valuable contribution to current knowledge.   It would be a surprise if he were ~ but anything is possible!  But from the little info you have given, it sounds very unlikely.

  3. citizenschallenge @1,

    You could also ask whether "anybody has seen or commented on":-

    Pangburn (2017)

    "Atmospheric carbon dioxide (CO2) and other trace greenhouse gases have little if any effect on climate."

    Pangham (2015)

    "Atmospheric carbon dioxide (CO2) has had no significant effect on average global temperature."

    Pangham (2014)

    "CO2 has no significant effect on climate."

    "Long term prediction of average global temperatures depends substantially on long term prediction of sunspot numbers"

    Pangburn (2008)

    "The conclusion from all this is that carbon dioxide change does NOT cause significant climate change."

    The lack of interest in Pangburn's work is evident in the total absence of reference to it within the scientific literature. But perhaps you ask why this lack of interest? Or what is the nature of the nonsense being so persistently peddled by Pangburn?

  4. MA Rodger @3 :

    Thank you for that info.   I had seen comments years ago on SkS by Dan Pangburn, and comments by him in more recent years on several blogs.  His scientific ideas show an overlap of crackpot & delusional aspects.   An interesting psychopathology ~ but far from rare in the sphere of climate denialism.

    Citizenschallenge ~  some googling quickly showed you having a minor clash with Pangburn nearly a decade ago.   With your inquiry at #1 , was it based on the discovery of something valid in "Pangburn 2021" ??   Had you any reason to suppose that a Stuffed Leopard would change its spots . . . or lose its stuffing?

    If you scroll down 2 days in the comments, you could have read the answer.

    Pangburn talking about water vapor as a GHG looking to the atmosphere ?  UUUUPS - he couldn`t see any clouds ??? -— Blind & stupid - like other deniers.

  6. Eclectic @4,

    Pangborn presents a long list of purile misconceptions which, if you are not familiar with the subject, can take a while to rattle out into the light-of-day.

    Thus in his latest masterpiece of nonsense linked above we have in Section 1 para 1:-

    "The radiation energy travels from ghg molecule to ghg molecule (or between surface and ghg) at the speed of light but dwells in each molecule for a few microseconds making the molecule warmer. The dwell time is also called the relaxation time and cumulative dwell time is what causes the GHE"

    It is not "a few microseconds" but on average "many microseconds" and, as atmospheric molecules do collide every "few microseconds", the radiation energy is almost always transferred from the flapping CO2 molecule to other atmospheric molecules. The far-more-numerous atmospheric collisions can set CO2 flapping as well as robbing the energy from a flapping one. As collisions are a product of temperature and and very very numerous, they are overwhelmingly responsible for setting CO2 molecules flapping, often enough for some of the flapping CO2 molecules to radiate-away the equivalent energy trapped from radiation by the CO2. The "cumulative dwell time" of individual molecues is certainly not "what causes the GHE."

    Section 1 para 2 is a bit garbled. The main error is in saying radiation escapes into space "Increasingly with altitude" . There is a quite distinct threshold altitude below which no radiation can escape, and above which all radiation can escape. The temperature of this threshold altitude (which varies with wavelength and GHG concentrations) is what determines how much radiation cools the planet.

    Section 1 para 3 arrives at a 1200-to-one ratio for surface/tropopause H2O levels which lookes like a back-of-fag-packet calculation as it is far too low.

    Section 2 talks of a "notch and 'hash'"  in the Earth's IR spectrum. (I assume notch=hash.) The notches in his Fig 1 are is actually due to the higher altitudes where CO2 & O3 are still absorbing their radation but where H2O is so defuse it is letting it out into space. The CO2 "notch" is not 18Wm^-1 but actually about 30Wm^-2, so causing directly about +8ºC of GH-effect and it is only through such planet-wide warming that the warming is "shared with (redirected to) WV molecules which radiate it to space" because it is now warmer at the altitudes where radiation can escape to space because higher temperatures mean more flapping molecules.

    And so the fool goes on. Pure nonsense through and through.

    Response: I don't think he has, but he did leave a comment at one of my old blog posts.  He seemed rather proud of himself and needed to share with anyone who gave a fart and guess I'm on his list.

    Thank you for sharing that list, Pangburn is nothing if not persistent.

    That is the question: the specific nature of his nonsense, shrunk down to a simple concise list.

    @4 Eclectic at 20:32 PM on 5 September, 2021 (to your question)

    Nope I don't expect the leopard to change his spot - I was looking for specifics regarding his claim, since his comment to me has me thinking about using it to build another post around - one that lays out his specific deceptions.  

    And though I have been proactively engaged and learning about climate science for over half century, I'm still not a scientist, so continue turning to them for my meat and potatoes so to speak.  They do a wonderful job of predigesting the data making it so much easier to digest.

    @5 coolmaster at 23:36 PM on 5 September, 2021, your's was the one disappointing comment though I very much appreciate your link - that will be helpful!  The snark I can handle, it's the vague cutzy inside riddles that drive me up a wall.  I'm a simple straightforward guy, looking for straightforward answers, be they information or insults, tell me what's on your mind, don't make me guess.  Just say'n.

    Badabing, badabang!!!  The jackpot comment.  Except for the time to work on it, I now have the materials at hand for creating that post, once I can carve out the time.


    Thank you all !

  8. MA Roger (Eclectic & coolmaster - it was an excellent link you shared)  I'm assuming you folks have no objection to being quoted and this thread cited?  

    "back-of-fag-packet calculation" ???? so that's even smaller than a back of cocktail napkin calculation.

    life is hard - and then you die

    If you are a simple straightforward guy, looking for simple answers - just read my comments of the last week. 

    You will find an alternative climate protection strategy.

    A concept to stop sea level rise - and global warming.

    It is so simple and straightforward that mostly nobody understands. ????

  11. Coolmaster:

    I have responded to your claim of an "alternate climate protection strategy" on the thread where you made the claim.

    Spolier alert: you are wrong.
